IMPROVEMENT IN PAPER=TUBE MACHINES.

Specification forming part of Letters Patent No. 158,354, dated January 5, 1875; application filed November 25, 1874.

To all whom it may concern:

Be it known that I, ASAHEL G. BATCHEL- DER, of Lowell, of the county of Middlesex and State of Massachusetts, have invented a new and useful Paper-Tube Machine; and do hereby declarethe same to be fully described in the following specification and represented in. the accompanying drawings, of which Figure 1 is a top View, Fig. 2 a side elevation, and Fig. 3 a longitudinal section, of the said machine.

In some respects it is analogous to the ma chine described in the United States Patent No. 95,670, dated October 12, 1869, and granted to Henry and James Douglass, each of the machines being to convert a strip of paper into a tube, to be subsequently reduced to short pieces, termed cop-tubes.

In my machine I employ a mandrel, a long rod or core; but, instead of using rollers therewith to turn or fold the strip of paper around it, I employ a series of elastic springs or fingers, each of which is curved where next the tube, so as not only to guide the paper, but turn it more or less down against the tube. These elastic springs not only guide the paper and turn it down upon the mandrel to better advantage than rollers, but they do not crease,

or wrinkle the paper as rollers are liable to do. Furthermore, with one of the springs a new result can be obtained, which cannot be effected by a roller-that is, the spring, when resting upon the paper, may be extended underneath the lap, so as to bend the paper down from the top of the mandrel laterally toward the other lap. The spring finger or bender to produce this effect I term the auxiliary inner-lap bender, it being hereinafter particularly described. Furthermore, I combine, with the core or mandrel and a mechanism for folding the paper around it laterally, a rotary tube or edge-layer, as hereinafter explained, its purpose being to gather in the laps and set down the outer lap of the paper upon the inner one. I also employ a rotary brush, an expander, and a tinisher, all of which are hereinafter explained.

In the drawings, A denotes the stationary core or mandrel, it being supported horizontally by a standard, B, bent in manner as shown at a. From the said standard B, another standard, G, and the base I) of the frame D, aseries of three elastic springs or benders, E, F, and G, extend, in manner and with respect to the mandrel A as represented, each spring or bender being, at or near its free end, curved laterally, so as to partially encompass the mandrel. The lowermost of these springs or elastic benders, viz., E, presses directly upward toward the mandrel. The second and third, viz., F and G, press horizontally and sidewise toward the said mandrel. The bender F is projected in advance of the bender Gr, and the latter in rear of the auxiliary bender H, which acts between the side benders F G, and presses downward the inner lap of the strip I of paper, in a manner to bend or press down said inner lap upon the upper half of the mandrel each way laterally from its top. In front of the benders is the rotary edgelayer K, which is a tube concentric with and encompassing the mandrel, and supported in a bearing in a standard, S, and provided with a grooved pulley, L, to receive an endless band for revolving the tube. There is projected from thepulleyabrush, M, which, while the pulley is revolving, moves with it around the mandrel, and presses down and brushes the strip of paper, and closes the lap and removes the surplus paste from the external surface of the strip. In advance of the brush the mandrel is formed conical or gradually expanded, as shown at N, and from thence it is cylindrical, as shown at O. The part N I term the expander, its purpose being to expand the tube, in order to make it of even bore throughout. Encompassing the cylindrical part 0 is a tube or finisher, P, supported by a standard, P. It acts on and finishes the extreme surface of the tube after the expansion of the tube. While the strip of paper, properly covered with paste, is being converted into a tube for being subsequently divided into what are termed cop-tubes, or tubes for any purpose, it is to be drawn through the machine by suitable means or mechanism.

I do not claim, for converting a strip of paper into a tube, a mandrel, a series of rollers, and a rotary brush arranged and combined in manner as represented and described in the United States Patent No. 95,670, to which allusion has hereinbefore been made.

I claim- 1. The combination of the mandrel A and the series of elastic benders E F G, arranged therewith substantially as set forth.

2. The combination of the mandrel A, the series of elastic handles E F G, arranged therewith as specified, and the auxiliary elastic bender H, to operate with the aforesaid series E F G, and between the side benders F G above the mandrel, in manner and for the purpose as explained.

3. The combination of the mandrel A, its series of strip-benders E F G, and the rotary edge-layer or tube K, arranged to operate with them as specified.

4. In combination with the mandrel A and its series of strip-benders E F G, the rotary brush M, applied to revolve around the mandrel, as explained.

5. The combination of the mandrel A, the rotary edge-layer K, the brush M, the expander N, the cylinder 0, and the finisher P, arranged and applied substantially in the manner to operate as specified.
